Patented ou. 1s, 193s This invention'ifrelatesto `'iiimprovementsY in,

The principal object of the invention is Y. 'f to the provision of awringer whichy ischaracter- .5 ized by a manual member that is'movable.from

a neutral'inoperative position -to an operative 4 position to put therolls under tension. or to release. the pressure, inl combination withdriving mechanism forfdrlving the roll lor rolls in oppoysite directionswhich includes a shiftable member movableV independently of ythe ymanualmember Vbetween operative and inoperative positions but movableby themanual member from `an operative position to an inoperative position tobring f l5 about stopping of -the--rolls and releasing of pressure. Bymeans of the novel features of the invention y the operator may move.the manual member'toan operative position to setthe rolls under,presser without engaging the driving mechanism. `With the rolls undertension the driving mechanism may then be engaged. In case the hand orother part of the operator becomes caught inthe rolls the operator bybringing up against the manual. member may swing it quickly toreleasethe pressure and simultaneously stop the drivingmechanism.

In the eventit is desired to reverse the direction of rotation of therolls or to stop them withv out releasing the' pressure, the shifter maybe moved for that purpose"independ ently of the manual member. H Y

' Altogether the ydriving mechanism may be engaged and disengaged bymovements of the shifter 35 quite independently v`of the movements YofAthe manual member which is movable for setting the rolls vunder tensionor for releasing them. i Where `the manual-member is in'an operativeposition with the rolls under tension and the shifter in an operativeposition wi'ththev rolls being driven the rolls are releasedfromftension andthe vdriving mechanism is disengaged by asimplefmovement 'of the manual memberto its neutral Vvinoperativeposition. n f y Heretofore it has been customary to bring aboutoperationof the driving mechanism by all moverments. of the manualVmember. This i's objectionmust now pass therebetween in a reversedirection.`

Furthermore, Y in! theY p rior art `wringers where clothes have becomelwound about the rolls and orri it is desired to reverse :the rolls tounwind the 5 clothes it, cannot be done without'releasing the tensionbecause itis diillcult if not impossible to restore, the, tension whenreleased with vclothes around aroll or rolls. According to thisinvention,the rolls may be reversed kwithout releasing the tension.

Various and `numerousfobjects and advantages of the invention will behereinafter morel fully referred to in connection .with theaccompanyingdescription of the preferred form thereof. ,In the drawings:r

To operate the wringer the manual member is swung to one v side or `theother fromv a.' central As it swings the engage ,the cam `surface 4tofthe receivers so that the 'manual memberl is relea'sably locked to thereceivers. According to the arrangement of* the springs the rolls.'whenthe manual member is locked` to the receivers, are undermore 'or lesstension andfexlert yielding pressure as material or cloth ,are passedbetweenthe rolls. Vlhe con- -1 struction described and its function issimilar to that describedl in the patent referred to and need not bedescribed more in detail here. When it becomes necessary or desirablethe manual' mem-.-

ber maybe released so as to release the pressure exerted bythe springs,by the operator bringing .up against rthe manual member with the arm orv hand to swing it to its neutral position. y

`The swinging` of the manual member from its K neutral inoperativeposition to operative position is independent of'any driving mechanismso the manual member lmay be releasably locked in operativepositionwithout danger of the operator Y. becoming caught or injured.. As willpresently yappear, the driving mechanism is set in operationindependently of the manualmember yet when the manual member is swung toinoperative neutral position the driving mechanism isautomaticallydisengagsd.

This rocker ill is moved by the manual member insuch away that it is associated therewith, and in some cases may be dispensedwith by arranging a projection such as Ill on the manual member itselfso that it may engage the lips of the bolt.

As previously described, the manual member Il may be swung to one, sideor thek other to an operative position away from its central neutralinoperative position. As it is so swung the rocker ill is swung therebyso that it assumes position ateither side of the centralposition shownin 4.
